| 摘 要： | 利用多变量统计学理论和矩阵变换，解决了在复杂信道模型下，难以对应用在MIMO系统中的空时码进行性能分析的难题，推导出平均成对差错概率的上界，得到了衰落信道相关性越强，系统误码性能越差的结论，最后的仿真结果说明理论推导结果是正确的．

| Abstract: | By using the theories of multivariate statistics a nd the matrix transformation, the difficulty in the performance analysis of the space-time code under complex channel model, which was applied to the MIMO system, was overcome. The upper bound of the average pairwise error probability of the space-time code was also derived. It is concluded that the more the fading channels correlate, the worse the performance of the system is. The simulation results indicate the correctness of the conclusion. |
